Definition of Onychogryphosis
Medically reviewed by Dr. Otari Nergadze, Neurosurgeon | Updated: January 2026
Onychogryphosis: an overgrowth (hypertrophy) and curving of the nails. Onychogryphosis results in a claw-like appearance of the nails and has been referred to as "ram's horn nails." It most often occurs due to neglect and failure to properly trim and care for the nails, although some cases have been described as occurring in response to repetitive trauma to the nail or nail bed. It is most commonly seen in the elderly.
